I was just trying to solve something I find to be very annoying in Solr: I just want some quick examples that are part of the actual example that I can go click on and try out w/o having to go chasing all over creation to find them (wiki, tutorial, various websites, etc.) Not too mention there is no simple "reference" for these examples, all of those things (wiki, tutorial) have a ton of verbiage around them. For instance, you have to scroll quite a long way in the tutorial to even get to a sample query. I just want a dumb little page, (ideally, it would actually be the landing page when hitting http://localhost:8983/solr when using the example) that shows me examples of interacting with Solr. I can click on the link, get results and then introspect what I just did.
Heck, going forward, we could even distribute the example index already built so that people don't have to do the indexing until later. I often find in my training classes that I get a lot better attention when I do search first instead of indexing.
Who knew such a simple thing was worth so much discussion.
